I think that this bug was triggered by "The Humble Bundle" when tried to install from software center with the application already opened. The software is there, in the screen of the Software Center but it crashes apt in the background.

At least it's what it seems to be...

To reproduce:
1. open software-center
2. click on "installed" in the top toolbar
3. click on "all software" in the top toolbar
4. search for a pacakge that is already installed (like "apt")
5. click on the details
-> crash

This bug was fixed in the package software-center - 5.4

  * lp:~mvo/software-center/lp1044141:
    - fix unicode error crash on a transaction error
      (LP: #1044141)
  * lp:~mvo/software-center/fix-size-calc-race:
    - fix crash due to a race in the size calculation code
      in the details view (LP: #1041004)
  * lp:~mvo/software-center/fix-crash-1048886:
    - No longer call GLib.init_threads() as this will cause
      LP: #1048886 later. Many thanks to Albert Astals Cid
  * lp:~mvo/software-center/dbus-idle-timeout:
    - stop the dbus data provider after 5min of inactivity
      (LP: #1058567)
  * lp:~mvo/software-center/lp1051829:
    - Do not report deb packages with lintian errors via the
      recoverable errors mechanism. This removes 97 out of 104
      instances of my sample of the recoverable error report
      for LP: #1051829. Other types of failures will still be
      reported as recoverable failures though (as we do want
      to know about them).

  * lp:~gary-lasker/software-center/lp1041004:
    - ensure that app_details is valid before using it (LP: #1041004)
  * lp:~gary-lasker/software-center/fix-crash-lp1021308:
    - send synthetic "style-updated" signals to ensure that the signal
      handlers are called on themes that do not send this signal (like
      oxygen-gtk3). This fixes a crash and broken drawing LP: #1021308

  [ Nicolas Delvaux ]
  * lp:~malizor/software-center/fix-lp1050036:
    - fix crash in get_label() (LP: #1050036) and drop the i18n for the
      yes/no symbols that were not translated in any language (as a result can also be dropped)
